Content of PhoneMeeting presentation (UPC)

Under:

Correlation between reco AL(+eta) vs. AL(-eta)

Under:

Study of correlation between AL(+eta) and AL(-eta), both determined from the same 8 statisticaly independent spin sorted yields.

11 Endcap W AL from 2012 Data Spin PWG

Under:

 See attached slides

10 AL for Z->ee

Under:

See attached slides.

09 Alternative rel lumi monitors

Under:

 Alternative methods of monitoring relative spin dependent luminosities for W AL analysis.

08 Q/PT charge separation

Under:

Transformation Q/PT --> Q * ET/PT is applied to remove hyperbolic correlation between reco electron charge reco in TPC vs. reco ET from EMC.

07 Preview of W AL(eta) from 2012 data for spin PWG

Under:

 Slides and writeups consistent with final eta-bin selection for 2012 W-data

06 2nd Endcap Bckg vs. EtaBin

Under:

To estimate QCD events passing W-algo with lepton limited to a narrow eta-range due to missing East Endcap we will use amount of events passing W-algo for the mirror eta-bin while West Endcap was d

05 W-algo pass-A through full 2012 data and MC

Under:

 Here are the EtaBin sorted histograms for the data and MC /star/u/stevens4/forJan/8.28.12/

For data day 84-86 are rejected.

01 RHIC polarization

03 Evaluation of Run 12 L2W preview production (P12ic) TPC calibrations

Under:

Here we present some plots from the recently produced L2W stream preview production announced here.

Polarized Tau Decay

Under:

In the background estimation for the W yields we account for W -> tau decays where the tau decays semi-leptonically to and electron and two neutrinos.

Comparison of AL for pp500 and pp510

Under:

 Using the CHE code (with DSSV and MRST2002) I compared W+ and W- AL for center of mass energy of 500 GeV (blue) and 510 GeV (

Bernd put together a Virtual Machine with both the CHE (NLO) and RHICBOS (Resummation) code, and directions for running these are posted.
